[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0011]
[First Embodiment of Hinge Device]
First, a first embodiment of the hinge device of the present invention will be described.
[0012]
FIGS. 1A and 1B are diagrams showing a configuration of a hinge device according to a first embodiment of the present invention.
[0013]
That is, in the hinge device according to the present embodiment, the bearing 2 is rotatably fitted to the hollow shaft 1. The cam plate 3 is also fitted to the hollow shaft 1.
[0014]
The cam plate 3 is formed by forming a cam portion 3a on a substantially circular plate-like member as shown in FIG. 1B. The cam portion 3a has, for example, a shape that is convex in the axial direction. Conceivable. A rotation restricting portion 3c is formed in the inner diameter portion of the cam plate 3, and the hollow shaft 1 is also formed in a shape corresponding to the rotation restricting portion 3c so that the hollow shaft 1 cannot rotate and can move in the axial direction. Be combined.
[0015]
On the other hand, the bearing 2 has an optional cam surface on a surface (not shown) corresponding to the cam plate 3 so as to mesh with each other. The cam surface provided on the bearing 2 is configured at a predetermined position so as to mesh with the relative rotation between the hollow shaft 1 and the bearing 2.
[0016]
Then, the spring 4 is arranged so as to be compressible and extendable around the hollow shaft 1 with respect to the free length. The extension of the spring 4 is regulated by the E-ring 6 fitted at one end to the cam plate 3 and at the other end to the hollow shaft 1 to prevent the spring 4 from coming off. The plate 3 is pressed against the bearing 2. In this embodiment, the spring 4 is a coil spring, but may be a disc spring. Further, the cam plate itself can be constituted by a disc spring.
[0017]
Therefore, when the cam portion 3a of the cam plate 3 and the cam surface (not shown) provided on the bearing 2 are engaged with each other, the rotation is restricted.
[0018]
Here, when a force is applied in the rotating direction so that the hollow shaft 1 and the bearing 2 are relatively rotated, the cam portion 3a of the cam plate 3 and the cam surface provided on the bearing 2 are disengaged from each other. The cam plate 3 moves to the left in FIG. 1A against the spring force of the spring 4.
[0019]
When the rotation is further continued, the cam plate 3 and the bearing 2 are rotated against the frictional force generated by receiving the spring force of the spring 4. Then, when the cam portion 3a approaches the cam surface at a different position provided on the bearing 2, the retraction of the two cams starts to engage with each other by the action of the cams without any rotation, and the cams 3a and 3b move together. Stabilizes at the position where meshes. The engagement and disengagement of the cam causes a click feeling of the user.
[0020]
Since the cam plate 3 can move in the axial direction with respect to the hollow shaft 1, the hollow shaft 1 and the bearing 2 move in the axial direction even when a click feeling occurs in the relative rotation between the hollow shaft 1 and the bearing 2. Absent.
[0021]
Of course, this movement is reversible, and the specifications required for the electronic device to which this hinge device is applied determine the stable position where the cam meshes, the operational feeling when rotating, the spring force, the cam shape, and the cam position. Is designed.
[0022]
Although not shown, a slit or a groove is formed in the inner wall of the outer cylinder 5 so as to mesh with the cam portion 3a of the cam plate 3. And is disposed so as to be prevented from falling off by the E-ring 6. The slit has a constant width in the axial direction so as not to hinder the movement of the cam plate 3 in the axial direction. With such a configuration, the outer cylinder 5 cannot rotate relative to the hollow shaft 1 via the cam plate 3.
[0023]
By configuring a hinge device having a click mechanism around the hollow shaft 1 in this way, functional members related to the function of an electronic device to which the hinge device is applied can be housed and arranged in the hollow shaft 1, and The space in the radial direction and the axial direction of the rotating shaft can be effectively utilized.
[0024]
[Second Embodiment of Hinge Device]
Next, a second embodiment of the hinge device of the present invention will be described.
[0025]
In this embodiment, a hinge device is configured without using a cam plate.
[0026]
FIG. 2 is a diagram illustrating a configuration of the hinge device according to the present embodiment.
[0027]
That is, the bearing 102 is attached to the hollow shaft 101 so as to be able to rotate and move in the axial direction. Further, a cam portion 101a is formed on the hollow shaft 101, and a cam portion 102a is also formed on the bearing 102, and positions for meshing with each other are provided at arbitrary positions. The spring 104 is assembled with the bearing 102 pressed by the E-ring 106. The E-ring 106 and the outer cylinder 105 are assembled so that they cannot rotate relative to the hollow shaft 101. In this case, the E-ring 106 and the outer cylinder 105 may be configured so as not to rotate relative to the hollow shaft 101 and the E-ring 106, respectively. Means for disabling relative rotation are not shown, but it is sufficient that each has a rotation restricting portion and meshes with each other.
[0028]
In such a configuration, when the bearing 102 is rotated with respect to the hollow shaft 101, when the cam comes off, the bearing 102 moves in the axial direction against the spring force of the spring 104, thereby disengaging the cam. . Other operations are the same as those of the hinge device according to the first embodiment.

[0063]
Here, in the hollow shaft 30 of the hinge device according to the present embodiment, the opening on the bearing 2, 102 side of the hollow shaft 1, 101 of the hinge device according to the first or second embodiment is closed. It is in such a form. This is to prevent the conversion lens, which is housed in the hollow shaft 30 and includes the lens frame 31 and the lens 32, from dropping through the opening into the shaft of the electronic device or into the device.
[0064]
In the hinge device and the hinge unit according to the present embodiment, the lid 34 is further detachably attached to the shaft portion 22b of the lower housing 22 of the electronic device.

[0067]
[Fifth Embodiment of Hinge Device and Hinge Unit and Fourth Embodiment of Electronic Device]
The present embodiment relates to a hinge device and a hinge unit having a plurality of hollow portions, and an electronic device using the same.
[0068]
That is, as shown in FIG. 14, one of the first to fourth embodiments, for example, two hinge devices according to the first embodiment are used, and each of the bearings is an integrated bearing 41. By using this, it is configured as one integral hinge device.
[0069]
Also, here, instead of providing a concave portion (or a convex portion) that engages with the electronic device on the outer peripheral portion of the hinge device as described above, a part of the bearing 41 is extended, and a mounting hole 41a is provided. Means for fixing to the housing of the electronic device. This fixing means can be similarly applied to the outer cylinder 5 described above.
[0070]
According to such a hinge device and a hinge unit, for example, the camera unit as described above is fixedly disposed in the hollow portion on the left side in FIG. 9, and is further illustrated in FIG. 13 in the hollow portion on the right side in FIG. 9. An electronic device in which such a conversion lens is detachably arranged can be configured.
[0071]
As described above, the hinge device is provided with a plurality of hollow portions, and the functional members are fixedly or detachably provided, so that it is possible to increase the added value while keeping the electronic device small. Further, since the hinge device is integrally formed, the unitization can be easily performed, and the assemblability of the electronic device can be improved.
[0072]
[Sixth Embodiment of Hinge Device and Hinge Unit and Fifth Embodiment of Electronic Device]
In this embodiment, a functional member is fixedly provided in one hollow shaft of the hinge device, and a detachable non-functional member is further added.
[0073]
FIG. 15A is a diagram showing a configuration of a hinge unit (hinge device) according to the present embodiment.
[0074]
That is, this hinge unit is a hinge device and a hinge unit having the same configuration as that of any of the first to third embodiments, for example, the first embodiment. , A lens 55 and a camera unit constituted by an image sensor unit, and a conversion lens unit constituted by another lens frame 52 and another lens 53 is detachably attached. Here, although not particularly shown, the conversion lens unit is detachably attached by a threaded portion on the inner wall of the hollow shaft 51 and a threaded portion provided on the lens frame 52 corresponding thereto. The mirror frame 54 and the lens frame 52 may be engaged with each other by screws.
[0075]
In this example, the conversion lens is configured as a wide conversion lens. According to such a configuration, the principal ray 56 at the time of the wide lens shown in FIG. 15A is configured as a lens having a wide angle of view 57, and is partially omitted, as shown in FIG. 15B. When the wide conversion lens is removed, the angle of view 59 of the lens becomes narrower than the wide angle of view 57. Even in this case, the chief ray 58 must be formed without being shaken by the hollow shaft 51. At this time, the hollow shaft 51 can function as a lens hood for preventing the incidence of unnecessary light.
[0076]
Although not shown, it is needless to say that the electronic apparatus according to the fifth embodiment can be configured by using such a hinge device according to the present embodiment.
[0077]
[Seventh Embodiment of Hinge Device and Hinge Unit and Sixth Embodiment of Electronic Device]
In the above-described camera unit, focus adjustment may be required at the time of assembling the camera unit due to its accuracy. Thus, the present embodiment enables such focus adjustment.
[0078]
A hinge device and a hinge unit according to the present embodiment will be described with reference to FIGS. Here, the case where the hollow shaft of the hinge device also serves as the lens frame will be described.
[0079]
As shown in FIG. 16A, in the present embodiment, the mirror frame of the camera unit is divided into a lens frame 61 and a sensor frame 62. Then, after the lens and the image sensor unit are assembled, they are connected via the respective screw units 61a and 62a. At this time, focus adjustment is performed by the screw portions 61a and 62a so as to form an in-focus image on the image sensor 12 for a subject at a predetermined distance.
[0080]
FIG. 16B shows a state in which the focus adjustment is completed. As described with reference to FIG. 1B, the sensor frame 62 has the rotation restricting portion 62b. If the cam plate 63 in FIG. 16A has a hole in a shape corresponding to this cross section, the cam plate 63 can move in the axial direction with respect to the sensor frame 62 holding the image sensor 12. And cannot be rotated.
[0081]
Here, the focus adjustment between the lens and the image sensor 12 is performed before assembling the click mechanism in the assembling process. As described above, the click mechanism is arranged around the lens frame 61 which is a hollow shaft in order to make the outer diameter of the hinge device smaller. Therefore, the hole shape of the cam plate 63 is also a shape corresponding to the outer shape of the lens frame 61. However, both the rotation restricting portion 61b of the lens frame 61 and the rotation restricting portion 62b of the sensor frame 62 after the focus adjustment are not necessarily located at the same position in the outer peripheral direction. Even in this case, the gap between the end face 61c of the lens frame 61 and the end face 62c of the sensor frame 62 is configured to be wider than the thickness of the cam plate 63 so that the cam plate 63 can be assembled. Accordingly, the cam plate 63 can be passed through the lens frame 61, rotated within the above-mentioned range, and assembled to the sensor frame 62, and can be assembled regardless of the position of each frame after focus adjustment.
[0082]
Although not shown, the electronic device according to the sixth embodiment can of course be configured by using such a hinge device according to the present embodiment.
